The objects of the invention -are to generate and produce mechanical power economically and 'in sufficient quantities for commercial use. Other objects are to secure mechanical motion for power purposes with simple and eiiic'ient appz'iratus,4 to produce a uniform speed regulated rotary motion under varying conditions of load, to utilize rictional clutch means between the elements subjected to the extremely variable' and sudden action of the waves' and surf and the rotative power element,V whereby danger of breakage is means beand speed power eleminimized, andy frictional pulley tween' the momentum retaining rotate the mechanical elements and ,mechanism that the-means of power production shall approach as nearly as possible automatic operationf y To attain the objects of the invention the mechanical elements thereof are incorporated in a new and novel combination consisting more particularly ot swinging paddies, means for converting the oscillating movements of the paddles, into' a'reciproeating linear motion, lmeans 'for transformiiigthe reciprocating motion into a continuous'rotary motion adaptable for actuating power appliances, and momentum means-to stabilize such rotary motion, the arrangement of the 'elementsbeing such that the translation'ol the latent energy of the ocean into direct mechanical energy isr accomplished with a minimum loss of power.

In. the severaly views like reference characters apply to like parts.

i platform frame l, supporting the rotating elements and g power transmission means, is mounted omsuitable piles 2, projecting above the ocean adjacent to the shore. The platform iframe is relatively disposed in a position with reference to the water to fully utilize thc-'wave'movements in actuatiiigpaddles 3, which are provided with braces l, preferably channel irons and disposed on the paddles in pairs lu ith the channels in opposed relation. Each pair oi braces 1l is slidablj engaged with corresponding pairs of swinging I beams 5 which are bolted to hubs t3 ot' shafts 7t respectively journaled in bearing bones 8 on the platform. Each pair of beams 5 is connected at v.te

is provided for adfnsting and retaining the paddles in position to be acted upon by the waves and surf, the vertical adjustment of 'the paddles most efectual in receiving power :notion iii n.1 rom, being maintained thereby.

is .13 connect brace rods S) with rel-itman cijrrocatuzg.; members 14, which slide in guides 15, preferably of channel iron, and mounted on journal bearing sujgiports 16.

The two shafts 17 are mounted to rotate in, bearing supports 1G and in longitudii'ial alin'cinent, A right hand spiral groove 18 formed in one shaft 17 and a left hand spiral groove 1S is formed .in the other shaft 1?. The reciprocating members 14 have cams 11.? projecting into the grooves 18 so that the shafts 17 are rotated back and forth as the members 14 reciprocate.

Through transmitting' clutches 2O a continuous rotary motion is .imparted to the intermediate shaft 21, each of the shafts 17 ha vingl a driving head carrying friction dogs 23, spring pressed into engagement with an enveloping cone 24, on the intermediate shaft. The paddles are so mounted to be successively acted upon by the advancing waves and surf. The intermediate shaft is tl'ierefore mounted between and in co-:icial alinement with alternately rotative spiral grooved shafts 17 which are successively rotated thi nigh suitable means by the paddle movements.

The dogs in the clutches 2O are set to work in opposite directions, so that when one clutch is working the other clutch is slipping, and vice versa, as required to drive the intermediate shaft 2l in one direction by the back and forth rotation ofthe shafts 17, so that power is imparted to the shaft 21 by the forward movement of one member 14 and by the bacini-ard movement of the other member 14.

The oscillating paddles 3 are constructed to efficiently receive the force' of the waves; `with this object in view, having flange faces curving outwardly, more or less, at the bottom as indicated at a to serve as a scoop for the power impulses of the waves; the impinglng face at o thus offering` greater resistance than the opposite convex non-resistant face 7; offers. The paddles 3 face in opposite directions, one to receive the force of the incominghv waves and the other to receive the force of the outgoing waves.

rlhe next successive step' in the conversion of wave power into mechanical` power is acconiolished by a counter sha1 t 2o, pulleys 26, 27, mounted respectively on the intermediateand counter shafts, and a transi'nission belt 28 connecting the pulleys 26, 2T. A driving` friction wheel 29 on the coincer shaft in Contact with the driven. friction wheel 30 on power shaft 31 provides .tartiner safety in power generation and affordsjr-.means of speed adjustment in connection with a centrifugal governor 32 and a momentum element or Hy wheel 38. The governor is driven by means of miter gears 34 from shaft 31 and nieves wheel 8O to and fro from periphery to center of driving wheel 2S). Driven friction wheel 3'0 is proY vided with a tongue engaging with longitudinal slot 3G in shaft 31, and hub 37 with a loose collar 3S in groove 38 of the hub, within which collar the hub rotates while having a linearmovement with respect to the shaft and rotating in conjunction therewith.

A connecting rod 39 extends between eollar 38 and collar 4() on the governor, having an angulaidisposition with reference to shaft 31 and driven wheel 3() whereby the vertical movement of governor collar 40 controls the position of said driven wheel with reference to the driving wheel 29 and is effective in regulating the speed. Driving wheel 29 is provided with a set screw 41 for adjustment to take up wear, with reference to driven wheel 30.'

The parts subjected to the greatest strain and wear in the transmutation of power, that is to say; the cams or teeth 19 are readily accessible for renewal, 'each cam comprising a block with oblong bearing faces 43 and a shank 44 which is held in corresponding recesses 45 in the reciprocating members 14 and detachable caps 46 thereon.

From the foregoing it may be seen that the translation of ocean energy into mechanical power is accomplished by simple elements, and that the transmission of the power is through elements having spiral engagement with one another, the arrangement being such that the intermittent movements of certain of the elements is resolved into a continuous motion maintained by a momentum retainer or fiv wheel element 33,

and made uniform by a governing element, all elements being thereby protected intheir movements relatively one to another against strain and breakage.
